This is a "digest" of 2008 polls that I have come across since Obama entered the landscape.
The general trend is that, Obama has essentially risen to the number two spot for the nomination in national polls, but in strategic vision state polls (covering some key states), Gore is in a strong second place, somewhat ahead of Obama. Edwards is hovering around 10% in most polls, and hence remains a factor.

First, Survey USA has released a MEGA 2008 poll of 60 different matchups, but they are available by subscription only, except for one free matchup per visitor. Results for some matchups can be found in this myDD diary.
